[Insert Technique Name]
[Insert Explanation]

Task 2. Selecting and setting up the DBMS environment

1.13 Before proceeding to PART 2, you must select an appropriate database management system (DBMS). Uptown IT uses Microsoft SQL Server, but depending on the context environment in which you are performing the tasks, you may have access to a number of server administration tools such as Microsoft SQL Server Management Studio or a similar tool. Set up the environment in preparation to start using SQL. The environment setup includes:

a) Access to the selected or available DBMS and administration tool
b) Access to an administrator account on the DBMS or a user account with permissions to create and alter tables.
c) Access to the century_inventions database. To install the database, you can use the century_inventions.bak or the century_inventions.sql file (database export file) and use it to import the database structure and data.

Paste in an appropriate screen image of your installed Century Inventions database: [Insert Screen Image]

1.14 Contingency task. Assume that you have attempted to import the data from the export/dump file, and two tables are not imported. All other tables are correct. You have used a text editor to view the file content, and all the data appears to be correct. This includes table structure and data.

What process would you follow to resolve the situation? [Insert Process]

PART 2. Create a database, create tables, alter table structure and table properties, and test the database with specific queries

TASK 1. Create database and tables

In this task, you must create a database and four (4) tables. This is just a subset of a database to test your practical skills on this topic. Before you start creating the tables and columns, you need to select a naming convention and use it consistently.

2.1 Create a database and name it: CarolinesClassroomRobots.

Paste in an appropriate screen image of your Caroline’s Classroom Robots database: [Insert Screen Image]

2.2 Using an appropriate naming convention, create four (4) tables using the details provided below for table names and column headings:

Table 1 – Class: ClassID, PrimaryLocation, TeacherName
Table 2 – ClassAttendance: AttendanceID, TeacherName, ClassID, DateCompleted, TimeCompleted, Note
Table 3 – Students: StudentID, FirstName, LastName, Email, ParentGuardianNames, ParentGuardianPhones, Note
Table 4 – ClassAttendanceLines: ClassAttendanceLineID, AttendanceID, StudentID, ArrivalTime, DepartureTime, Note

Data for these tables are provided as CSV and Microsoft Excel files, and these will give you an indication of what data types are required for the fields. You do not need to import the data into the tables; this is done in a later question. Provide screen images of the tables once created.

Paste in an appropriate screen image (or images) of your tables for your Caroline’s Classroom Robots database: [Insert Screen Images]

2.3 Identify the relation and cardinality ratio between the four tables and create appropriate foreign keys (FK). Provide a small diagram (a mini ERD) that displays the table relationships and the cardinality ratio (e.g., one-to-one or many-to-one)

Paste in a copy of your mini ERD for your Caroline’s Classroom Robots database: [Insert Mini ERD]

2.4 Identify and properly create the primary keys (PK) for each table. The PK must be set to auto_increment. (What you need to submit for this item is noted below.)

2.5 For each column, select the appropriate precision parameters. These may include: data type, range, attributes, default value, uniqueness, and nullability. (What you need to submit for this item is noted below.)

2.6 For each table, identify the foreign keys (FKs) and set up the required relationships between the tables. (What you need to submit for this item is noted below.)

2.7 Once the tables have been created, identify which columns have been indexed by the system and explain why.

Paste in an appropriate screen image of the Relationships screen from your Caroline’s Classroom Robots database: [Insert Screen Image]

Export a data dictionary or SQL script that lists or demonstrates that you have completed items 2.4-2.6. The name of your associated output file is: << Filename >>

Or…
Go into each table design, right-click on a field, and go to indexes/keys. Investigate the indexes on each table.

Task 2. Alter table structure

2.8 Write an SQL statement to alter the Class table and include an extra column named Notes (use the appropriate naming convention selected in Task 1).

Paste in your SQL Statement: [Insert SQL Statement]

2.9 You have discovered that the Email field in the Students table is not large enough for some email addresses. Write an SQL statement to alter the Student table to ensure the email field is twice as large as before.

Paste in your SQL Statement: [Insert SQL Statement]

2.10 Alter the ClassAttendanceLines table to add CHECK constraints to ensure that the Arrival Time never has a time entered prior to 7 am.

Paste in your SQL Statement: [Insert SQL Statement]

Task 3. Populate the database using CSV files

2.11 Using the .txt files provided in the assessment folder, import the data into the corresponding tables. Each worksheet or .txt file corresponds to one of the tables:

Class.txt
ClassAttendance.txt
ClassAttendanceLines.txt
Students.txt
If there are issues with the imported data, please identify the problem and provide a solution or explanation of how you would resolve the issue.

Paste in an appropriate screen image of your Class table with imported data: [Insert Screen Image]

Paste in an appropriate screen image of your ClassAttendance table with imported data: [Insert Screen Image]

Paste in an appropriate screen image of your ClassAttendanceLines table with imported data: [Insert Screen Image]

Paste in an appropriate screen image of your Students table with imported data: [Insert Screen Image]

Task 4. Testing tables with specific queries (6 queries)

Using the tables you created, write and execute the following SQL queries:

2.12 Retrieve the details of all the classes taught by a teacher named “John Smith.”
